Abstract:
An object of the present invention is to provide, at a low cost, a solar cell having high conversion efficiency. A solar cell according to the present invention is characterized by including a passivation film that protects a semiconductor substrate, a first finger electrode connected to the semiconductor substrate on a main surface of the semiconductor substrate, a first bus bar electrode that intersects the first finger electrode, and an intermediate layer provided in an intersecting position of the first finger electrode and the first bus bar electrode. The solar cell is characterized in that the first finger electrode and the first bus bar electrode are electrically connected to each other via the intermediate layer.
